Manager Colin O'Brien rotated his side following Ireland's 3-1 win over Slovenia on Tuesday as Conor Coventry, Joe Dwyer and Aaron McColgan all started.
With the slightly cooler conditions on Thursday morning in Brdo, Ireland played with a high tempo and dominated the early stages.
Ireland should have gone ahead with 10 minutes gone as Marcus Rawley crossed for Thomas Caffery at the back-post but he placed his shot wide.
Ireland went ahead soon after as a good move down the right allowed Lee O'Connor in behind and his low cross was placed home by Gavin Kilkenny in the 17th minute.
Slovenia pulled level after the break as a right-sided corner was headed home at the back post in the 66th minute and despite late chances for either side, the points were shared.
Manager O'Brien believes it has been a productive week for the side and has praised the quality of the performances from his squad.
O'Brien said: "We changed the team around today as much as we could with injuries with certain players. It's important that all 20 players get as much time on the pitch as possible.
"The conditions were a bit cooler today than Tuesday's game and that really helped us start the game with a high tempo which saw us take the lead.
"The players showed good discipline and stuck to the defensive strategy so I'm disappointed with conceding from a set-play but that is something we can correct.
"Overall, it's been a very productive week which has given us a great opportunity to assess the players. We've executed some bits well and most importantly, the squad have had some good exposure and minutes on the pitch."
